2015-03-25CRISv32: add device tree supportRabin Vincent1-0/+4
Add support for booting CRISv32 with a built-in device tree. Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
2012-10-02UAPI: Partition the header include path sets and add uapi/ header directoriesDavid Howells1-1/+3
Partition the header include path flags into two sets, one for kernelspace builds and one for userspace builds. Add the following directories to build after the ordinary include directories so that #include will pick up the UAPI header directly if the kernel header has been moved there. The userspace set (represented by the USERINCLUDE make variable) contains: -I $(srctree)/arch/$(hdr-arch)/include/uapi -I arch/$(hdr-arch)/include/generated/uapi -I $(srctree)/include/uapi -I include/generated/uapi -include $(srctree)/include/linux/kconfig.h and the kernelspace set (represented by the LINUXINCLUDE make variable) contains: -I $(srctree)/arch/$(hdr-arch)/include -I arch/$(hdr-arch)/include/generated -I $(srctree)/include -I include --- if not building in the source tree plus everything in the USERINCLUDE set. Then use USERINCLUDE in building the x86 boot code.

2009-09-20arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0Sam Ravnborg1-2/+0
Albin Tonnerre <albin.tonnerre@free-electrons.com> reported: Bash 4 filters out variables which contain a dot in them. This happends to be the case of CPPFLAGS_vmlinux.lds. This is rather unfortunate, as it now causes build failures when using SHELL=/bin/bash to compile, or when bash happens to be used by make (eg when it's /bin/sh) Remove the common definition of CPPFLAGS_vmlinux.lds by pushing relevant stuff to either Makefile.build or the arch specific kernel/Makefile where we build the linker script. This is also nice cleanup as we move the information out where it is used. Notes for the different architectures touched: arm - we use an already exported symbol cris - we use a config symbol aleady available [Not build tested] mips - the jiffies complexity has moved to vmlinux.lds.S where we need it. Added a few variables to CPPFLAGS - they are only used by the linker script. [Not build tested] powerpc - removed assignment that is not needed [not build tested] sparc - simplified it using $(BITS) um - introduced a few new exported variables to deal with this xtensa - added options to CPP invocation [not build tested] Cc: Albin Tonnerre <albin.tonnerre@free-electrons.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Mikael Starvik <starvik@axis.com> Cc: Jesper Nilsson <jesper.nilsson@axis.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Cc: "David S.

2009-04-21CRIS: Merge machine dependent boot/compressed and boot/rescueJesper Nilsson1-7/+7
Merge the machine dependent boot directories for v10 and v32. This avoids some code duplication and eases the way for further merging later on. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
2008-10-31[CRIS] Remove links from CRIS buildJesper Nilsson1-42/+19
Remove the links to architecture and machine dependent directories (boot, lib, drivers, arch, mach) The links were created and used mostly from the arch/cris/Makefile, so why not dispense with them altogether? Changed $(ARCH) to "cris" in Makefile, it is easier to read this way. The CRISv32 head.S common files for the kernel and compressed images needed to be modified to use ifdefs instead of using the now removed mach link. Since there are only two versions, this is not a huge loss in readability. The link to vmlinux.lds.S is also replaced with a merged version which uses ifdefs to select the correct layout. System.map before and after are identical. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com> Acked-by: Sam Ravnborg <sam@ravnborg.org>
2008-10-31[CRIS] Merge asm-offsets.c for both arches into one file.Jesper Nilsson1-4/+2
Eliminates the link to arch specific asm-offsets.c from CRIS architecture build system. Resulting asm-offsets.s are identical before and after change for both arch-v10 and arch-v32. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com> Acked-by: Sam Ravnborg <sam@ravnborg.org>
2008-10-29[CRIS] Move header files from include to arch/cris/include.Jesper Nilsson1-17/+9
Change all users of header files to correct path. Remove some unneeded headers for arch-v32. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
2008-10-13CRIS: proper defconfig setupAdrian Bunk1-0/+2
This patch moves the cris defconfigs to arch/cris/configs/ where they belong. As a side effect they can now be used directly through e.g. make ARCH=cris artpec_3_defconfig The default defconfig is set through KBUILD_DEFCONFIG.

2008-02-08CRIS: Update main Kbuild makefile.Jesper Nilsson1-69/+70
- Remove old and non-generic targets, use generic ones instead. - Add sub-arch as mach-fs or mach-a3 for EtraxFS and Artpec-3 respectively. - Add links to sub-arch directories, and erase before trying to create them. - Include from sub-arch specific include directory "mach". - Add files to be cleaned in CLEAN_FILES instead of as archclean target.
2007-10-15kbuild: enable 'make AFLAGS=...' to add additional options to ASSam Ravnborg1-1/+1
The variable AFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of AFLAGS with KBUILD_AFLAGS all over the tree. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k, s390 Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-10-14kbuild: enable 'make CFLAGS=...' to add additional options to CCSam Ravnborg1-4/+4
The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

2006-01-21cris: asm-offsets related build failureAl Viro1-1/+1
fallout from "kbuild: cris use generic asm-offsets.h support" - symlink target was wrong Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2005-09-11kbuild: rename prepare to archprepare to fix dependency chainSam Ravnborg1-1/+1
When introducing the generic asm-offsets.h support the dependency chain for the prepare targets was changed. All build scripts expecting include/asm/asm-offsets.h to be made when using the prepare target would broke. With the limited number of prepare targets left in arch Makefiles the trivial solution was to introduce a new arch specific target: archprepare The dependency chain looks like this now: prepare | +--> prepare0 | +--> archprepare | +--> scripts_basic +--> prepare1 | +---> prepare2 | +--> prepare3 So prepare 3 is processed before prepare2 etc. This guaantees that the asm symlink, version.h, scripts_basic are all updated before archprepare is processed. prepare0 which build the asm-offsets.h file will need the actions performed by archprepare. The head target is now named prepare, because users scripts will most likely use that target, but prepare-all has been kept for compatibility. Updated Documentation/kbuild/makefiles.txt.

2005-09-09kbuild: cris use generic asm-offsets.h supportSam Ravnborg1-8/+2
Cris has a dedicated asm-offsets.c file per subarchitecture. So a symlink is created to put the desired asm-offsets.c file in $(ARCH)/kernel This is absolutely not good practice, but it was the trick used in the rest of the cris code. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+112
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
